In Granada, Spain, there are a bunch of such "cave dwellings" in the hill above the Alhambra Palace, from the inside looking quite similar to the photo in this story, small rooms with lime whitewash on the walls. I was graciously invited for an evening in one of those places, and while it was a bit cramped, and maybe a bit roughly furnished (you must use an out-house in most cases, if you were wondering, and the plumbing and electricity can be a challenge), it was agreeable and the temperature stays in a comfortable range in temperate climates. Here's an interesting and brief travel documentary featuring some info on the cave dwellings in the second half: http://www.youtube.com/watch?v=iMdeBviSO4I http://www.youtube.com/watch?v=iMdeBviSO4I And though I hate to link to the Daily Fail, they do have a nice little overview guide of Granada with a good picture of the cave dwellings from the outside and a bit of historical info here: http://www.dailymail.co.uk/travel/article-569192/Granada-Destination-Guide.html http://www.dailymail.co.uk/travel/article-569192/Granada-Des... P.S. Go see Granada!
